Neuropsychology of Early-treated Phenylketonuria: Specific Executive Function Deficits 总被引:14,自引:0,他引:14

This study explored the hypothesis that children with early-treated phenylketonuria (PKU) are selectively impaired on executive function measures, even when still on diet. The rationale for this hypothesis is that even mild elevations in phenylalanine (Phe) can lead to lower central levels of biogenic amines, including dopamine (DA). We hypothesize that this mild DA depletion causes subtle prefrontal dysfunction, which in turn affects executive functions such as set maintenance, planning, and organized search. 11 preschool early-treated PKU children (M age = 4.64) and a sample of age- and IQ-matched unaffected peers (n = 11) were evaluated on a battery of executive function (EF) measures. In addition, a "non-executive function" task, recognition memory, was administered to all subjects. Group comparisons demonstrated that PKU children were significantly impaired on an executive function composite score; there were no group differences, however, in recognition memory. These results supported the hypothesized specific deficit in executive function. Furthermore, within the PKU group the executive function composite score was significantly negatively correlated with concurrent phenylalanine levels, even after controlling for the correlation between IQ and executive function skills. This second finding provides support for the proposed biochemical mechanism underlying the specific cognitive deficits. 相似文献

Pigeons responded to changeover-key concurrent variable-interval variable-interval reinforcement schedules while there were intervals during which the changeover key was inoperative (no-choice intervals). In Experiment 1, a multiple schedule on the changeover key signaled choice and no-choice intervals. All subjects showed near-perfect discrimination during initial discrimination training and rapid reacquisition of discrimination following contingency reversals. In Experiment 2, the onset of no-choice intervals was unsignaled and contingent on interchangeover time. The temporal distribution of changeover-key responses conformed to the temporal distribution of choice intervals. The results of both experiments suggest that changeover responding is modifiable as a function of its immediate consequences. The results of Experiment 2, in particular, suggest that time or some correlate of time since the last changeover response can determine subsequent changeover behavior. 相似文献

This article draws on a case study of 15 boys aged between 13 and 14 years who attend an urban ethno-centric community school located in Melbourne, Australia. The study investigated how the boys' constructions of masculinity were mediated by a strong connectedness to their Greek cultural traditions and ideals. Data generated from focus group discussions provided insights into the complex ways in which the boys individually and collectively constructed their understandings of what it means to be a man. For most boys, maleness constituted cultural traditions and behaviours that must be learnt: a code of conduct which a boy acquires from his elders that is talked into existence and transmitted through a hegemonic discourse. Yet the findings also revealed the agency boys can exercise and the fluidity of their configurations: contradictions and inconsistencies being an inherent part of the recursive process of their gendered identity formation. 相似文献

This article is a study of the competing academic and professional identity frameworks of lecturers whose discipline has only
recently become part of the business of higher education. The article engages with important questions about higher education
change and purpose, standards and parity among disciplines. Taking a critical ethnographic approach, it combines policy discussion
of shifting higher educational and nurse education regimes with an insider investigation into the attempts of a group of new
nurse lecturers in a pre-1992 English university to make sense of their work and identity in an already contested site. These
experiences and perceptions are analysed from the perspectives of autonomy, status and rival knowledge regimes. By underlining
the diversity of lecturer experiences in these terms, the article contributes to discussion of new stratification. It suggests
that despite the apparent merging in many respects of professional and academic frameworks, higher education practitioners
in such newly ‘academic’ disciplines can still find traditional professional identities more reliable conferrers of meaning
than academic ones. 相似文献

This study examined whether gaining access to a new digital device enhanced the digital media literacy of young adults and what factors determine such change. Thirty-five young adults were given a mobile tablet device and observed for one year. Participants engaged in an online community, responding regularly to online surveys and discussion forums. Digital media literacy, using multidimensional scales, was measured at the beginning and end of the study. Usage was measured every month to track changes over time. When measured with multiple dimensional scales, the participants’ digital media literacy levels increased over time. Those who used the tablet device for information access and social activities increased their digital media literacy in some dimensions. However, an increase in digital media literacy was not directly related to the time spent on the tablet. 相似文献

What play therapists do within the therapeutic relationship of humanistic/non-directive play therapy
Sally Robinson 《Pastoral Care in Education》2013,31(3):207-220
Play therapists are increasingly being employed in schools, yet there is confusion among many health, education and social care practitioners about the role of play therapists. This paper explains how play therapists position themselves and what they do through an examination of the therapeutic relationship between the therapist and child. It discusses the core conditions of congruence, acceptance and empathy with reference to recent research. Play therapists vary their practice in terms of verbal or non-verbal interaction, the tools in their playroom and how they physically place themselves. This paper argues for placing an emphasis on the non-verbal mirroring of the child, the incorporation of expressive media such as paint, clay and sand into the play room and the positioning of the therapist within the play space. 相似文献

Modular A‐level courses, indeed modular forms of assessment in many areas of education, have gained in popularity over the past few years. This research looked at data collected as part of the ALIS (A‐level Information System) project. In particular, the attitudes, future academic intentions and attainment of students gaining a grade in A‐level Mathematics were compared, by gender, between those who followed a modular course and those who were assessed at the end of two years of study. The two groups were found to have a similar average GCSE grade, but overall, the final A‐level grades of those assessed modularly were half a grade higher than their linearly assessed contemporaries. Possible reasons for these differences are discussed. The types of teaching style employed in modular and non‐modular A‐level courses were compared. Initial findings suggest that modularly assessed courses are relying even more on a didactic approach. 相似文献

The study of aging can bridge divisions between biology, social sciences, and humanities, develop an understanding of causal interrelationships, and help in distinguishing between fact and opinion. An introductory course in gerontology should, therefore, be firmly tied to the liberal arts core of higher education, and not merely provide an assembly line of facts. Why particular problems have been investigated is as worthy of discussion as the findings themselves. The practical implications of research deserve emphasis, but the aim of university education is not to train pressure groups. Undergraduates should be helped to appreciate difficulties in designing and interpreting gerontological studies, as well as to realize that they are not yet ready to undertake independent empirical investigations. The work of the first author is supported by the Canadian National Research Council (APA 89) and the Department of National Health and Welfare. 相似文献

ABSTRACTGraduating students must be prepared with knowledge and skills for the financial aspects of social work practice. This study examines graduating students’ attitudes and perceptions about client finances, as well as their financial knowledge. Internet survey results (n = 116) of BSW and MSW graduating students indicate that respondents (a) perceive a limited function for discussing client financial circumstances in practice, (b) understand the relevance, however, of client finances, (c) are unprepared to address this aspect, and (d) are supportive of integrating this content into required policy and practice courses. Teaching and curricular implications, along with programmatic recommendations, are included. 相似文献

Although the close relationship between education and the middle class has long been recognised in the sociology of education, its various dimensions have rarely been examined in detail. Through investigating the educational histories and occupational destinations of 199 recruits into the middle class, this paper explores whether there is any clear connection between educational pathway and occupational location. In particular, it analyses the cohort's various careers against suggested cleavages within the middle class (professional/managerial, symbolic/material, public/private). The data indicate that educational pathways influence occupational locations along a number of directions. Some schools, notably those that are private and academically selective, feed a greater proportion of students into high-status universities and out into high-status occupations. However, in terms of the level of occupation, the status of university seems more important than the school. Whether a school is public or private does not appear to have influenced the choice of a managerial or professional career path, but school sector may contribute to horizontal differentiation of middle classes in terms of whether they take up employment in the public or private sector. The data suggest that schools reflect and reinforce contrasting allegiances to private and public forms of educational provision that then influence sectors of employment and political preferences. 相似文献
